QUASAR^TM Platform HD

The QUASAR^TM Heavy Duty Respiratory Motion Platform simulates patient motion for QA of motion-guided radiation therapy systems with phantoms up to 45 kg. It offers multi-directional motion, including sagittal and user-defined rotations. Its simple design integrates easily into adaptive QA protocols for comprehensive respiratory motion management testing.

Features

Heavy Duty

Equipped with a large 45 cm x 35 cm platform surface and accommodating up to 45 kg (100 lbs), the QUASAR™ Heavy Duty Respiratory Motion Platform is able to integrate multi-directional motion to most of the industry’s large-scale phantoms.

Simplicity

Modus QA has developed an easy-to-use phantom with comprehensive testing capabilities for demanding motion protocols in modern radiation therapy departments. From its manual operation mode to its rapid 30° offset alignment wedge, the QUASAR™ Platform HD is an intuitive motion-management QA tool designed with the end-user in mind.

Motion Control Options

Easily adjust motion waveform amplitude and frequency with either local manual control at the motor or advanced programmable control at the software interface. Apply a user-defined rotated arrangement to your existing phantoms to create complex motion profiles. With playback of motion waveforms, complexity is elevated to test the limits of your motion management systems.

Motion Precision

The QUASAR™ Platform HD exhibits detailed sensitivity when replicating captured or created waveforms. A highly responsive motor repositions the translation stage every 10 ms (100x per second) providing real-life breathing replication. Waveforms from 0-60BPM are easily replicated with sub-millimeter accuracy, allowing for the testing of a large range of clinical protocols.

Versatility

The QUASAR™ Platform HD is compatible with any stationary phantom up to 45kg (100lbs). Specialized feet support allows for the rapid indexing of the phantom in either a linear or 30° rotated offset arrangement for multidirectional motion capabilities. With acceleration and velocity parameters set correctly (according to the weight of the phantom), imported waveforms can be analyzed and modified so that they playback safely.

Software

The intuitive programmable respiratory motion QA software is included with the QUASAR™ Heavy Duty Respiratory Motion Platform. This locally-installed package enables the control of the phantom’s motion and customization of supplied and imported motion waveforms. An incorporated Deep Inspiration Breath Hold Function increases workflow efficiency for users to test DIBH protocols.

Complex Motion Control Options

The Platform HD offers full control of your phantom’s motion profile. Our Respiratory Motion QA Software offers multiple operation modes to increase utility. From adjustable sinusoidal waveforms and simple test patterns to accurate playback of complex waveforms, the platform offers the flexibility to choose your motion complexity for your required testing sequence.

Customizable Waveforms

In addition to an extensive library of pre-loaded waveforms, the Respiratory Motion QA Software enables the import of acquired waveforms from a number of respiratory gating and motion tracking systems. The waveforms are completely customizable, improving the user experience when modifying waveform patterns to achieve the desired testing protocol.
